Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, the following detailed description of the embodiments of the present application will be made with reference to the accompanying drawings.
The air conditioner constant temperature dehumidification control method can achieve a good constant temperature dehumidification effect, and improves user experience.
The first embodiment,
Fig. 1 is a schematic structural diagram of an air conditioner to which the constant temperature dehumidification method of the air conditioner provided by the embodiment of the invention is applied.
In fig. 1, 101 is a compressor, 102 is an outer machine fan blade, 103 is an outer machine heat exchanger, 104 is an outer machine expansion valve, 105 is an inner machine fan blade, 106 is inner machine electric heating, 107 is an inner machine heat exchanger, 108 is an outer machine control main board, and 109 is an inner machine electromagnetic valve.
It should be noted that fig. 1 is only a schematic diagram of the structure of the air conditioner, and the portions not related to the embodiment of the present invention are simplified and omitted.
The air conditioner constant temperature dehumidification operation mode will be described based on the air conditioner configuration shown in fig. 1.
When the air conditioner is started in the constant-temperature dehumidification mode, the rotating speed of the outer machine fan blades 102 is reduced, and the outer machine expansion valve 104 is opened, so that the refrigerant with higher outdoor temperature directly flows into the inner machine heat exchanger 107, namely the indoor evaporator. Referring to fig. 1, the indoor evaporator is divided into two parts, and the middle part is connected in series by an inner machine electromagnetic valve 109. When hot refrigerant passes through the electromagnetic valve, the refrigerant is throttled to be low-temperature refrigerant, so that cold and heat are offset, and constant temperature is formed in a room.
However, when the outdoor weather temperature is high or when the outdoor environment is not easy to dissipate heat, the temperature of the outer unit heat exchanger 103, i.e., the condenser, is too high, which may cause the temperature of the outer unit control main board 108 to be too high, and may easily cause the main board components to be burned out if the outer unit control main board is operated for a long time.
Fig. 2 shows a flowchart of an air conditioner constant temperature dehumidification control method according to an exemplary embodiment of the present application.
Referring to fig. 2, the air conditioner constant temperature dehumidification control method provided by the present application may include steps 201 to 203.
Step 201: and acquiring the temperature of an outdoor heat exchanger of the air conditioner.
In some embodiments, the step of obtaining the temperature of the outdoor heat exchanger of the air conditioner is performed when the air conditioner is operating in the constant temperature dehumidification mode. Because the air conditioner operation is when constant temperature dehumidification mode, the fan blade rotational speed of outer machine reduces, and when the external environment was hotter, the too high condition of outdoor heat exchanger temperature probably appeared, influences the safety and the stability of components and parts, consequently needs to adjust the running state of air conditioner based on outdoor heat exchanger temperature.
Step 202: and judging whether the temperature of the outdoor heat exchanger is greater than or equal to a preset heat exchanger temperature threshold value or not.
When the temperature of the outdoor heat exchanger is greater than or equal to the preset temperature threshold of the heat exchanger, the fact that the outdoor heat exchange is not smooth is indicated, and the situation may cause damage caused by overhigh operating temperature of the main board.
Optionally, the preset heat exchanger temperature threshold is 50 ℃.
After step 202, the method for controlling constant temperature and dehumidification of an air conditioner according to the embodiment of the present invention may further include:
and if the temperature of the outdoor heat exchanger is smaller than the temperature threshold of the heat exchanger, maintaining the original running state.
In some embodiments, when the external environmental conditions are good, and the temperature of the outdoor heat exchanger is not too high for a while, the operation state of the air conditioner does not need to be adjusted.
Step 203: if the temperature of the outdoor heat exchanger is greater than or equal to the temperature threshold of the heat exchanger, the rotating speed of an outdoor fan and the temperature of the electric heating pipe are increased, so that the temperature of the outdoor heat exchanger is reduced, and the temperature of the indoor environment where the air conditioner is located is kept constant.
In some embodiments, if the outdoor heat exchanger temperature is greater than or equal to the heat exchanger temperature threshold, the rotation speed of the outdoor fan and the temperature of the electric heating pipe are increased, which may include steps 301 to 303.
Step 301: and increasing the rotating speed of the outdoor fan to a preset first rotating speed, and increasing the temperature of the electric heating pipe to a preset first temperature.
In some embodiments, the method may further include acquiring a set temperature of the air conditioner set by the user and an indoor ambient temperature in which the air conditioner is located.
In some embodiments, the first temperature is greater than the indoor ambient temperature.
Specifically, the increasing of the rotating speed of the outdoor fan to the preset first rotating speed means increasing the lower initial rotating speed of the outdoor fan to the preset first rotating speed in the constant-temperature dehumidification state.
Optionally, the initial rotation speed is 200r, and the first rotation speed is 500r.
After the rotating speed of the outdoor fan is increased, the outdoor heat exchanger is fully radiated, so that the temperature of a refrigerant entering the indoor evaporator is greatly reduced, and the temperature of the indoor environment is reduced.
In order to maintain a constant temperature environment indoors after the rotation speed of the outdoor fan is increased, the temperature of the electric heating pipe is increased.
Optionally, the first temperature Td = Tc +10 ℃, tc being the indoor ambient temperature.
The condition that water is blown from the air inlet of the air conditioner internal unit can be avoided by raising the temperature of the electric heating pipe to be higher than the indoor environment temperature. In practical use, if the temperature of the electric heating pipe is lower than the indoor environment temperature, the gas in the air is dehumidified by the evaporator, and the temperature is reduced after dehumidification, so that condensed water is formed. If the temperature of the electric heating pipe is higher than the temperature of the dehumidified dry pellets, condensation is not easy to form, and therefore air port blowing of an air conditioner indoor unit is avoided.
Step 302: and judging whether the change value of the temperature of the outdoor heat exchanger meets a preset first condition or not and judging whether the change value of the indoor environment temperature meets a preset second condition or not after first preset time.
In some embodiments, the first predetermined time is 10 minutes.
Optionally, the first condition is Δ Tb ≦ 3 ℃. If the temperature of the outdoor heat exchanger can be reduced by 3 ℃ after ten minutes, the temperature of the outer condenser can be effectively reduced by operating the outdoor fan at the first rotating speed.
Optionally, the second condition is that Δ Tc is ≧ 0 ℃. If the indoor environment temperature can not be reduced after ten minutes, the temperature of the electric heating pipe can reach the indoor constant temperature requirement.
Alternatively, the second condition may be set to Δ Tc ≧ 1 ℃ or Δ Tc ≧ 2 ℃.
Step 303: if the change value of the temperature of the outdoor heat exchanger meets the first condition and the change value of the indoor environment temperature meets a preset second condition, the rotating speed of the outdoor fan is maintained to be operated at the first rotating speed, and the temperature of the electric heating pipe is maintained to be operated at the first temperature.
The air conditioner constant temperature dehumidification control method provided by the embodiment can timely cool down and ensure that an inner machine can provide accurate heat and keep an indoor constant temperature state in a constant temperature dehumidification function when the temperature of a main board is too high. Through mutual adjustment of the rotating speed of the outdoor heat exchanger and the auxiliary heating temperature of the electric heating pipe, the temperature of the outdoor condenser can be finally reduced, the safety and reliability of the control main board of the outdoor unit are guaranteed, meanwhile, the indoor temperature is not reduced, and the comfort degree of the indoor environment is kept.
Example II,
The method for controlling constant temperature and dehumidification of the air conditioner provided by the embodiment of the invention comprises steps 201 to 203, wherein the process of adjusting the rotating speed of the outdoor fan and the temperature of the electric heating pipe in the step 203 can comprise steps 301 to 303.
After step 302, the method for controlling constant temperature and dehumidification of an air conditioner according to the embodiment of the present invention may further include other adjusting processes.
Step 201: and acquiring the temperature of an outdoor heat exchanger of the air conditioner.
Step 202: and judging whether the temperature of the outdoor heat exchanger is greater than or equal to a preset heat exchanger temperature threshold value or not.
Step 203: if the temperature of the outdoor heat exchanger is greater than or equal to the temperature threshold of the heat exchanger, the rotating speed of an outdoor fan and the temperature of the electric heating pipe are increased, so that the temperature of the outdoor heat exchanger is reduced, and the temperature of the indoor environment where the air conditioner is located is kept constant.
In some embodiments, if the outdoor heat exchanger temperature is greater than or equal to the heat exchanger temperature threshold, the step 301 to the step 303 may be included to increase the rotation speed of the outdoor fan and the temperature of the electric heating pipe.
Step 301: and increasing the rotating speed of the outdoor fan to a preset first rotating speed, and increasing the temperature of the electric heating pipe to a preset first temperature.
Step 302: and judging whether the change value of the temperature of the outdoor heat exchanger meets a preset first condition or not and judging whether the change value of the indoor environment temperature meets a preset second condition or not after first preset time.
If the change value of the outdoor heat exchanger temperature meets the first condition and the change value of the indoor environment temperature does not meet the second condition, executing step 401: and maintaining the rotating speed of the outdoor fan to be a first rotating speed, and increasing the temperature of the electric heating pipe according to a preset temperature gradient at intervals of the first preset time until the change value of the indoor environment temperature meets the second condition.
In some embodiments, the first predetermined time is 10 minutes.
In some embodiments, the preset temperature gradient is increased by 10 ℃ every ten minutes.
After step 401, the method may further comprise step 402: and if the temperature of the electric heating pipe reaches a preset maximum temperature value and the change value of the indoor environment temperature does not meet the second condition, reducing the running frequency of the compressor.
In some embodiments, if the temperature of the electric heating pipe reaches a preset maximum temperature value (for example, 60 ℃), the indoor temperature will still drop and cannot be kept constant, the compressor is limited to reduce the frequency, and the dehumidification effect of a smaller part is sacrificed to maintain the indoor temperature constant.
If the variation value of the temperature of the outdoor heat exchanger does not meet the preset first condition, executing step 501: and increasing the rotating speed of the outdoor fan according to a preset rotating speed gradient at intervals of the first preset time until the temperature change value of the outdoor heat exchanger meets a preset first condition.
In some embodiments, the first predetermined time is 10 minutes.
In some embodiments, the predetermined speed gradient is increased by 100r every ten minutes.
In some embodiments, after step 501, the method may further include step 502: and if the rotating speed of the outdoor fan reaches a preset maximum rotating speed value and the temperature change value of the outdoor heat exchanger does not meet the first condition, reducing the running frequency of the compressor.
In some embodiments, if the rotation speed of the outdoor fan is increased to a preset maximum rotation speed value (e.g., 800 r), and the temperature of the outdoor condenser is still too high, e.g., higher than 55 ℃, the compressor is limited to reduce the frequency, and the dehumidification effect of a smaller part is sacrificed to prevent the temperature of the outdoor heat exchanger from being too high, so as to protect the main board components.
In some embodiments, after step 501, the method may further include step 503: and if the change value of the indoor environment temperature does not meet the second condition, increasing the temperature of the electric heating pipe according to a preset temperature gradient at intervals of the first preset time until the change value of the indoor environment temperature meets the second condition.
The constant-temperature dehumidification method of the air conditioner provided by the embodiment of the invention can perform feedback control on the rotating speed of the outdoor fan and the temperature of the electric heating pipe according to the running condition of the air conditioner after the rotating speed of the outdoor fan and the temperature of the electric heating pipe are adjusted, so that the constant-temperature dehumidification effect of the air conditioner is further improved.
Example III,
Fig. 3 shows another flow chart of the air conditioner constant temperature dehumidification control method provided by the invention in real time.
Referring to fig. 3, in some embodiments, the air conditioner constant temperature initial control method provided by the embodiments of the present invention may include the following processes.
After the air conditioner enters the constant temperature dehumidification mode to operate, the temperature Tb of the outdoor heat exchanger, the temperature Tc of the indoor environment, the temperature Td of the electric heating pipe and the set temperature Te are detected.
And detecting whether the temperature Tb of the outdoor heat exchanger is greater than or equal to 60 ℃, and if not, maintaining the current operation. At the moment, the outdoor heat exchanger does not have the situation of overhigh temperature and does not need to be adjusted.
If the temperature Tb of the outdoor heat exchanger is greater than or equal to 60 ℃, further judging whether the difference value between the set temperature and the indoor environment temperature is greater than or equal to 2 ℃, namely judging that T delta = Te-Tc is greater than or equal to 2 ℃, and if not, increasing the rotating speed of the external fan to V2 and enabling the electric heating temperature to be greater than or equal to Tc +20 ℃.
If the difference between the set temperature and the indoor environment temperature is greater than or equal to 2 ℃, the rotating speed of the outer fan is increased to V1, and meanwhile, the electric heating is started, wherein the electric heating temperature is greater than or equal to Tc +10 ℃. After the operation is carried out for 10 minutes in the state, whether the temperature change delta Tb of the outdoor heat exchanger is less than 3 ℃ or not and whether the temperature change delta Tc of the indoor environment is less than 0 ℃ or not are judged.
If the above conditions are met, the rotating speed of the outer fan is maintained to be V1, and the electric heating temperature is greater than or equal to Tc +10 ℃ to continue operation.
If the condition is not met, the rotating speed of the outer fan is increased to V2, and the electric heating temperature is greater than or equal to Tc +20 ℃ for operation.
The constant-temperature dehumidification control method of the air conditioner provided by the embodiment of the invention realizes a constant-temperature dehumidification process through the electromagnetic valve, starts electrical heating when the temperature of components is overhigh in a unit, controls the temperature through linkage of the electrical heating and the temperature of the external fan and the temperature of the condenser, and can take energy conservation and user experience into account on the premise of preventing the temperature of the components from overhigh.
Examples IV,
The air conditioner constant temperature dehumidification control method provided by the embodiment of the invention is further explained by taking a specific application scene as an example.
In a specific application scenario, the outdoor temperature on a certain day is high, for example up to 30 ℃.
After the user starts the constant temperature dehumidification function, the temperature of the outdoor condenser is too high, for example, more than 50 ℃, because the rotating speed of the external fan is very low and is only 100r to 200 r. At this time, the rotation speed of the outdoor fan is increased to 500r, and the rotation speed is increased to cause the temperature of the indoor heat exchanger to be reduced, for example, from 30 ℃ to 24 ℃. In order to keep the indoor temperature constant, the auxiliary electric heating is required to be started, and the indoor electric heating temperature is controlled to be 40 ℃.
After the indoor electric heating temperature is adjusted to 40 ℃ and the operation is carried out for ten minutes, the judgment is carried out. If the temperature of the outdoor condenser is reduced by more than 3 ℃, the fact that the rotating speed of the outer fan is 500r at the moment is effective for heat dissipation of the outdoor condenser is shown, and the outer fan can continue to operate according to the rotating speed of 500r. Meanwhile, if the temperature of the indoor heat exchanger can be maintained at 30 ℃, the indoor electric heater operates at 40 ℃, and the indoor temperature can be maintained to be stable.
And if the temperature of the outdoor condenser is reduced by more than 3 ℃ after the indoor electric heating temperature is adjusted to 40 ℃ and the outdoor condenser is operated for ten minutes, but the indoor temperature is reduced, which indicates that the electric heating power can not meet the requirement of constant indoor temperature, adjusting the indoor electric heating temperature to 50 ℃, and operating for ten minutes and then checking again. If the requirement of constant indoor temperature cannot be met, the indoor electric heating temperature is continuously increased until the electric heating temperature reaches 60 ℃.
If the electric heating temperature reaches 60 ℃, the requirement of maintaining the indoor temperature stably can not be met, the frequency of the compressor is reduced, for example, 2hz is reduced every minute, and judgment is carried out every ten minutes of operation until the operation is stable or the frequency is reduced to the lower limit of the frequency operation.
In summary, the constant temperature dehumidification control method for the air conditioner provided by the embodiment of the invention can solve the problems of little indoor heat and temperature reduction caused by increasing the rotating speed and heat dissipation of the outdoor unit in the constant temperature dehumidification process of the air conditioner. Meanwhile, the problem of different heat supplements under different indoor cooling conditions can be avoided, and the energy-saving effect is achieved. In addition, in the method provided by the embodiment of the invention, cold and hot gases do not intersect, so that the problem of condensed water generated by the intersection of the cold and hot gases can be avoided. Compared with the prior art, the constant-temperature dehumidification control method only adopts the dehumidification mode and the electric heating linkage control mode, namely, the method adopts the electric heater to realize the constant-temperature dehumidification function and adopts the electric heating as the heat source for constant-temperature dehumidification.
